Whether this is a sign of the Mets desperation for a fifth starter (thats's right Livan Hernandez is currently our 4th starter) or Tim Redding is 100% healthy, that will be determined on Monday night against the team with the best record in the NL.

Tim Redding will be activated from the disabled list and make his Mets debut, in a start, on Monday night, against the Dodgers.
Redding was signed this off-season to compete for the fifth starters spot and his 2.25MM contract guaranteed him at least the long man role in the bullpen.
He had off-season toe surgery, which left him out of shape entering spring training and when he tried to rush things, he ended up aggravating his throwing shoulder.
After spending the better part of a month in Port St. Luice, working on conditioning and rehabing the shoulder, he made two starts in Buffalo. Both starts were no-decisions, his ERA was 2.77 in 13 innings of work.
Tim Redding will come off the DL for the first time all season this weekend in time to make a start Monday night in Los Angeles against the Dodgers. source NY Post
